    hello, If im using a 200 watts cab (8 @ ohms) into a 300 watts (300W@8ohms, 500W@4 ohms) head, it can damage the cab?

    and if im using 2 cabs of 200 watts (8 @ ohms) into the same head, it take out 400 (at 4@ohms) watts?
    is this combination will damage the 200 cabs as well? how many watts will come out from each cab?

    The watts you're putting out depends on how high up your master volume is and how hard you are playing.
    This isn't a constant output. (More on this in the FAQ)

    It should be fine, such 2 cabs and such head.
    If you are putting to much power in your cabs you will hear it.
    Speakers start to fart out.
    Use your ears.

    Realisticly, you will rarely need to turn up your master volume so high that you are pumping to many watts into your cabs.
    Unless you are in a really loud band and play big venues.

    Sounds like you're doing okay with the modestly-powered rig described. Use some common sense and be realistic in your volume output, though. Stupid behavior results in speaker damage.

    If you hook (2) 8 ohm cabs into the parallel outputs on the rear of the amp, the amp will "see" a total 4 ohm speaker load with a resulting ~250 watts per enclosure.
